ABSTRACT

An aqueous oxidative colouring composition for keratin fibres has at least one oxidative dye precursor and optionally at least one coupling agent and an aqueous emulsion of divinyldimethicone/dimethicone copolymer with an internal phase viscosity of more than 1×10 8  mm 2 /s measured at 0.01 Hz and at about 25° C. and at least one alkyl ether or ester or amine alkyl amine or quaternary ammonium compound.

The present invention is related to an aqueous oxidative colouringcomposition for keratin fibres especially human hair.

Hair colouring has been widely practiced for ages. The colorations aredivided into two main groups, the first being permanent colourationbased on mainly oxidative hair dyes which penetrate into hair andpolymerize, and the second is based on direct dyes which is, withoutexcluding any penetration, mainly adsorbed onto hair and widely based oncationic and neutral dyes. In the latter, recently compositions based onanionic direct dyes have also been made available by the applicant whichdeliver brilliant, shiny and long lasting colours.

In hair colouration, one of the purposes is certainly change the haircolour and/or cover any inhomogeneous hair colours in particular greyhair. Another purpose is to refresh shine, brilliance and vibrancy ofhair colour. Especially in hair shine wide variability has been observedand there is, therefore, need for further improvements.

Hair colouration, especially oxidative hair colouring may damage thehair which may further cause that hair becomes difficult to combthrough, is not smooth, difficult to manage and has too many fly-aways.It is therefore, desirable to have hair colouring compositions whichdoes not have at least one of these disadvantages and optimally none ofthese disadvantages.
